This topic explains the Ruby Laser, one of the first solid-state lasers, in a clear and exam-oriented manner for Engineering Physics students (RGPV syllabus).
The discussion begins with a brief introduction to lasers and the principle of stimulated emission, followed by a detailed explanation of the construction of a Ruby Laser, including the ruby rod, optical resonator, flash lamp, and energy levels of chromium ions (Cr³⁺).

The working of the Ruby Laser is explained step-by-step, covering optical pumping, population inversion, metastable state, and laser emission at 694.3 nm. This content is useful for B.Tech 1st year exams, numerical understanding, and viva preparation under RGPV Engineering Physics.
